To assemble this study, WalletHub compared 182 of the largest cities -- the 150 most populated, and at least two of the most populous in each state -- around three primary dimensions: 1) Emotional & Physical Well-Being, 2) Income & Employment and 3) Community & Environment. Those were broken down into 31 metrics, like depression rate, income-growth rate, and average leisure time spent per day. Those metrics were graded on a 100-point scale and combined into an overall score that was used to rank the cities.
It may come as some surprise that the top city is Plano, Texas, which, to say the least, doesn't come up very much. Maybe because it doesn't feel the need to bring attention to itself, as it's already so happy? The North Texas city near Dallas came in at number four for lowest separation & divorce rate and in the top 10 for all three of the overarching categories. Right behind Plano is Irvine, California, which has the obvious benefit of being located in California, plus being number five in overall Community & Environment, second lowest for separation and divorce rate, the second highest for sports-participation rate. Bros, it seems, really do have more fun.
In dead last is Detroit, which came in 181st (second to last) for Emotional & Physical Well-Being, Income & Employment, and Community & Environment, and also had the highest separation & divorce rate of any of the cities. That's not to say it's impossible to be happy in Detroit, or that the people there are miserable, but you're probably not doing yourself any favors in that department by moving there.
Also, we know money can't buy happiness, but we're also going to suggest checking out this list of cities with high paying jobs.
